Any reference to unofficial game modifications is strictly forbidden. |

The Dungeon Developers Development Kit (DDDK) allows anyone to develop modifications or new maps for Dungeon Defenders. You can even create a total conversion, changing aspects of the Dungeon Defenders source and create their own content and games. Packaged with the game’s complete source code and art assets, the Dungeon Defenders Development Kit is one of the definitive Unreal reference codebases for anyone looking to create their own Unreal games.
Installing[]
To download the DDDK, open up the main steam window (Library). Under the 'All Games' drop down menu, select 'Tools()'. Find 'Dungeon Defenders Development Kit' and right click and select Install, or just double click. Follow any prompts to download and install.
Using[]
Once installed the DDDK will show up in your steam game list but will throw an error. We can hope Trendy will fix this in the future but for the time being you have to run DunDefTool.exe manually. By default it is located at 'C:\Program Files\Steam\steamapps\common\Dungeon Defenders\Binaries.

Error Fixes[]
- Failed to find package core for async preloading, can be fixed by rebuilding scripts.
Updates[]
- Pre 9.0.0
- Updated Compatibly for map cooking for versions 9.0.0 and higher.
- Fixed crashing issue with Taley Mines Packages.
- Fixed textures breaking when a level is cooked to the Steam workshop.
- 7.47
- Upgraded Dungeon Defenders Development Kit to 7.47, with ALL up-to-date game content including Tower Wars, Akatiti, and Holiday 2012 Contents. Also fixed in the DDDK: cooking maps with sublevels now works, and now all original maps can be successfully cooked without having to set "Is Official Map" to False.
- 7.38e
- Dev launcher will automatically update the existing Steam Workshop Entry (if any) when you try to Publish a Cooked Map to a different Steam Workshop Title. (Some users were getting confused about how to update their maps, so this will make it easy for them to do so by having it automatically update the existing Workshop entry.)
- 7.38
- Integrated Steam Workshop, and DDDK now automatically cooks for both Mac and PC. You can browse and add maps from the Steam Workshop while in-game, and if you join a Workshop map that you don't already have downloaded, the Workshop subscription page for that map is automatically opened for you. Most usefully, moved all Custom Missions to their own Mission Setup tab, rather than putting them in the "Challenges" section.
- 7.28b
- Updated DDDK to 7.28b
- 7.27
- Fixed DDDK TC Crash due to outdated TC scripts
- 7.26c
- DDDK updated to 7.26c
- 7.18b
- Updated DDDK to 7.18b, including new precompiled shaders.
- 7.14e
- DDDK updated to 7.14e including example assault map (Tree of Life assault)
History[]
The DDDK was first released on November 11th, 2011 as a DLC. With the 7.40 patch it is now a separate download. Before that, you could not uninstall it without uninstalling Steam too.
